I saw iNioxin Conditioner in Winners in Barrhaven Market center. $30 (1000ml)?. I am using Nioxin shampoo and conditioner for a while because I heard "用着不掉头发" too. But I did not see significant difference. There are many types of Nioxin, like no.1.2.3.4.5. I am not sure how to choose the type that fit to the hair.
